In, the high alundum (Al2O3) of fusing point is not melted at this temperature, substantial amounts of can be deposited in ceramic surface, the ceramic crackle of increase
Convex line thickness, strengthens the modelling effect of convex line bar.
In the present invention second leaching glaze be preferably ceramic semi-finished product is immersed in colored glaze slip, immersion the time be 5~
10 seconds, take out standby after drying, the present invention does not have particular/special requirement to drying means, using this area conventional drying methods.
In the present invention, colored glaze slip color as needed, adds 3~10% (glaze slip in glaze slip
Mass percent meter) chemicals, preferably include in glaze slip 5~7% chemicals；The chemicals is preferably oxidation
Copper, zirconium silicate, cobalt oxide or chrome green；According to the depth of required color, the addition of chemicals, root can be selected
According to the concentration of required glaze slip, the addition of water can be selected.
In the present invention carry out second soak glaze in add colored chemicals purpose be to multicolour on ceramics,
Ceramic semi-finished product is immersed after colored glaze slip, because the moulded pottery not yet put in a kiln to bake of ceramic semi-finished product does not have porcelain also, with water absorbing properties.So
Moisture content in glaze slip penetrates into from gap to be absorbed, and glaze cannot be introduced into gap, so as in cracks accumulation, form higher caliper
With the convex line bar that third dimension is strong.
In the present invention, second firing includes heating and thermostatic process, and the temperature-rise period is preferably included by room temperature
Rise to 1120~1240 DEG C；Second firing time is 10~14h, preferably 11~13h；
In the present invention, it is preferred to temperature-rise period be divided into two stages：Heating-up time first stage is 1~4h, heating speed
Rate is 180~270 DEG C/h, and heating rate is preferably 220~260 DEG C/h, more preferably 240 DEG C/h, second stage
Heating-up time is 4~14h, and heating rate is 100~180 DEG C/h, and heating rate is preferably 120~160 DEG C/h, more excellent
Elect 150 DEG C/h as.Currently preferred thermostatic process is between heating first stage and second stage.
In the present invention, the time of the standing is preferably 1~7 day, more preferably 3~4 days；In the present invention, crackle one
As be just to start slowly to produce after kiln discharge, therefore, it is necessary to through standing after a while, can just be formed in ceramic surface
Crackle.Time of repose is long, then crackle is more close；If time of repose is short, crackle is few and thin.
In the present invention, second cooling is preferably to be naturally cooling to 200~280 DEG C, and opening wicket makes kiln temperature
It is down to room temperature；In the present invention, the temperature after the Temperature fall is preferably 220~260 DEG C, is more preferably 250 DEG C.
The method that the middle temperature that the present invention is provided fires underglaze colour color crackle convex line bar ceramics, ceramic paste preforms body is spontaneously dried
Afterwards in immersion intermediate glaze slurry, obtain soaking glaze ceramic paste preforms body；Obtained leaching glaze ceramic paste preforms body is fired, obtained after cooling
Semi-finished product；The second leaching glaze, the second firing are carried out after the semi-finished product are stood successively, the second firing is only fiery after terminating, through second
Cooling obtains underglaze colour color crackle convex line bar ceramics；Wherein second firing includes heating and thermostatic process, and the temperature-rise period is
1120~1240 DEG C are risen to by room temperature；The component of glaze slip, includes by percentage to the quality used in second leaching glaze：Kaolin 80~
95%, feldspar 5~20%.The present invention fires intermediate glaze slurry on ceramic body, using the principle of its cold cracking, makes base substrate table
The glaze layer in face is cracked, and soaks glaze carrying out second, because base substrate does not magnetize also, also with water absorbing properties, glaze slip will heap
The cracks that product is fired in first time, being formed has relief crackle, while kaolinic master in glaze slip used in the second leaching glaze
It is alundum (Al2O3) to want composition, and its fusing point is 2054 DEG C, in the temperature-rise period for rising to 1120~1240 DEG C by room temperature, and fusing point is high
Alundum (Al2O3) do not melt at this temperature, can effectively be deposited in ceramic surface, the thickness of the ceramic convex line bar of increase is carried
The non-skid property of high ceramics, the ceramics that warm therapy is fired during intermediate glaze slurry of the present invention is combined can also meet anti-seismic performance and heat endurance
The requirement of energy.And middle temperature firing process reduces firing temperature compared with high-temperature firing method, the reduction of its energy consumption, production cost
Reduce therewith.
